The solution for angled stair connections. Provides a flat bearing surface for your tensioners on sloped posts. Finished in premium Black Titanium PVD.

Overview

Ensure a secure and professional installation on your staircase with RiaYer 30° Beveled Washers. When installing cable railing on stairs, standard flat nuts or heads cannot sit flush against the post due to the angle. These washers correct that geometry, creating a perfectly flat surface for your hardware to tighten against.

Finished in our signature Black Titanium PVD, they match perfectly with black cable railing kits and offer superior resistance to rust and corrosion thanks to their T316 Marine Grade construction.

Why Do You Need These Washers?

• 📐 Solves the Angle Problem: Designed with a standard 30-degree angle (fitting most staircases between 25°-35°). They act as an adapter between your angled post and the flat nut of your tensioner.
• 💎 Black Titanium PVD Finish: We use advanced Vacuum PVD Plating to bond the black color to the stainless steel. It won't chip or peel like paint, ensuring your washer stays black even when you tighten the metal nut against it.
• 🛡️ Protects Your Hardware: Without these washers, tightening a nut on an angled surface bends the threaded stud, causing structural weakness. These washers ensure the force is distributed evenly.
• 🌊 T316 Marine Grade: Made from solid T316 Stainless Steel, suitable for indoor and outdoor applications, including harsh coastal environments.
• 🔧 Wide Compatibility: With a 1/4" inner diameter (ID), these are designed to fit most standard 1/8" and 3/16" cable railing terminals and stud tensioners.

How to Install:

1. Drill: Drill your holes through the post at the angle of the stairs.
2. Place: Place the Beveled Washer on the post surface. Orient it so the angle of the washer counteracts the angle of the post, creating a vertical flat face.
3. Insert: Insert your threaded stud or receiver through the washer.
4. Tighten: Screw your nut or head against the flat surface of the washer. The washer ensures a solid, flush fit.

FAQ

Q: My stairs are 35 degrees. Will this work?
A: Yes. While designed as 30 degrees, these washers typically accommodate stair angles between 25 and 35 degrees effectively.

Q: Why Black PVD instead of powder coating?
A: Washers endure high pressure when you tighten the nut. Powder coating (paint) would crack and peel under this pressure. PVD is molecularly bonded, so it withstands the tightening force without losing its black color.

Q: What hardware does this fit?
A: It has a 1/4" hole, making it perfect for most 1/8" cable railing kits that use Threaded Studs, Receiver Terminals, or Swage Studs.

Q: Can I use this on wood and metal posts?
A: Yes, it works on both. It provides a flat landing spot regardless of the post material.
